Paraffine Hydrotreating Catalyst takes modified alumina as carrier, carrying such active components as tungsten and nickel and special promoter, featuring high activity at low temperature, good stability, good compression resistance and abrasive resistance, and easy loading and unloading, etc. It can be recycled after regeneration.
1. Application
It is mainly used to produce food-grade paraffin and medicine-grade Vaseline. It has been successfully used in several industrial units of SINOPEC and PETROCHINA. When the operating pressure is 12Mpa, the light stability of hydro-treated product can reach sy+2, even sy+1.
